Answer:

372 - 12.26 = 359.84

372 > 12.26

The difference is 349.84, and I know this because I substracted 12.26 from 372. I know that Sam has more money because 12.26 is less than 372

In order to estimate the mean amount of time computer users spend on the internet each month, how many computer users must be s

Sladkaya [172]

Answer:

The minimum sample size required is 5,499 computer users.

The major obstacle is that it is a big sample size if it is a small organization wanting to perform it.

Step-by-step explanation:

We need to calculate a sample size in order to have 95% confidence interval with 12 minutes of witdth.

So, we have that the difference between the upper limit and the lower limit is 12:

$UL-LL=12$

$(\mu+z*\sigma/\sqrt{n})-(\mu-z*\sigma/\sqrt{n})=12\\\\2z\sigma/\sqrt{n}=12\\\\\sqrt{n}=(1/6)*z\sigma\\\\n=(1/36)z^2\sigma^2$

For a 95% CI, the value of z is 1.96. The standard deviation is 227.

$n=z^2\sigma^2/36=(1.96)^2*(227)^2/36=3.8416*51,529/36=5498.72\\\\n=5499$

The minimum sample size required is 5,499 computer users.

A 2018 Chevrolet Suburban averages 15 miles per gallon of gas in the city. It drives 47% farther per gallon of gas on the highwa

solmaris [256]

Answer:

On the highway, the cost to drive per mile is $2.21

Step-by-step explanation:

In the city the average distance per gallon is 15 miles

On the highway, he can drive 47% farther;

The distance he can cover on the highway per gallon will be;

15 + 47% of 15

= 15 + 0.47(15)

= 15 + 7.05 = 22.05

So on the highway, he can travel a distance of 22.05 miles

So the cost per mile on the highway would be;

$3.25 for 15 miles

$x for 22.05 miles

so we have the cost to drive per mile on the highway as;

(3.25 * 15)/22.05 = $2.21

Answer:

Question 1: g = 6

Question 2: v = 84

Question 3: y = 60

Question 4: w = 496

Question 5: Kyle had $400 to begin with.

Step-by-step explanation:

Question 1 explanation: 12g = 72 ⇒ g = $\frac{72}{12}$ = 6

Question 2 explanation: $\frac{v}{4}$ = 21 ⇒ v = 21 * 4 = 84

Question 3 explanation: $\frac{1}{6}$ y = 10 ⇒ 6 * $\frac{1}{6}$ y = 10 * 6 ⇒ y = 60

Question 4 explanation: w + 376 = 872 ⇒ w = 872 - 376 = 496

Question 5 explanation: K - 85 = 315 ⇒ K = 315 + 85 = 400, so Kyle had $400 originally in his account.
